Objective To establish HPLC-DAD method for the simultaneous determination of 23-acetate alisol B, ferulic acid, verbascoside, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, gastrodin, chrysophanol, aurantio-obtusin, calycosin 7-O-β-D-glucopyranoside, and hyperoside in Shenqi Shiyiwei Granule (SSG). Methods The chromatographic separation was achieved on an Waters XBridge-C18 (250 mm×4.6 mm, 5.0 μm) column with methanol-acetonitrile-water (15:80:5) and methanol-0.1% phosphoric acid (10:90) as mobile phases for gradient elution, at the flow rate of 1.0 mL/min; The column temperature was 35℃.Results The linear ranges of 23-acetate alisol B, ferulic acid, verbascoside, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, gastrodin, chrysophanol, aurantio-obtusin, calycosin 7-O-β-D-glucopyranoside, and hyperoside were 0.4-8.0 μg/mL (r=0.999 2), 0.2-4.0 μg/mL (r=0.999 5), 0.2-4.0 μg/mL (r=0.999 5), 0.1-2.0 μg/mL (r=0.999 6), 0.1-2.0 μg/mL (r=0.999 7), 0.1-2.0 μg/mL (r=0.999 4), 0.5-10 μg/mL (r=0.999 2), 0.6-12 μg/mL (r=0.999 2), 0.4-8.0 μg/mL (r=0.999 4), 1.0-20 μg/mL (r=0.999 6), and 0.8-16 μg/mL (r=0.9993). The average recoveries (n=6) were 98.1% (RSD=0.9%), 98.1% (RSD=1.6%), 99.1% (RSD=1.6%), 98.3% (RSD=1.8%), 99.5% (RSD=1.5%), 99.9% (RSD=0.6%), 98.5% (RSD=0.7%), 100.4 (RSD=0.8%), 101.6% (RSD=0.4%), 99.7% (RSD=0.9%), and 101.2% (RSD=1.1%), respectively. The contents of nine batches of 23-acetate alisol B, ferulic acid, verbascoside, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, gastrodin, chrysophanol, aurantio-obtusin, calycosin 7-O-β-D-glucopyranoside, and hyperoside were 0.081-0.089, 0.261-0.269, 0.060-0.069, 0.038-0.047, 0.030-0.037, 0.042-0.049, 0.420-0.428, 0.141-0.151, 0.178-0.189, 0.107-0.117, and 0.069-0.078 mg/g. The results showed that there was little difference among the batches. Conclusion The method is accurate, sensitive, credible, and repeatable. It can be applied to the quality control of SSG.
